It's already known that the “healthy glow” of a tan actually represents damage to skin cells.
But a new study of people on vacation has found that sunbathing also can disrupt the skin's microbiome, altering the populations of bacteria that live on the skin in ways that could be harmful to health.
The microbiome recovers within a month, but during that time a person will be more ...
Golfing may be a great way to get outdoors and enjoy the pleasures of a classic summer pastime. But a new study warns that walking the greens for hours on end without adequate sun protection may notably increase the risk for skin cancer.
Researchers in Australia found that more than one-quarter of golfers in that country have been diagnosed with skin cancer at some point, making Auss...
Newer sunscreens that can match your skin tone may encourage more people to use sunscreen, an expert says.
"The lighter a person's skin, the higher their risk for skin cancer," said Dr. Henry Lim, former chair of dermatology at Henry Ford Hospital in Detroit. "While people with darker skin have a lower risk for s...
Children at risk for multiple sclerosis (MS) might find some protection from the disease by spending more time in the sun, a small study suggests.
Although MS is rare in children and young adults, those with relatives who have the condition have increased odds of developing the disease early. Exposure to sunlight may cut their risk in half, researchers say.
Most people know that sun-sourced vitamin D is good for their bones. So could avoiding the sun to reduce skin cancer risk weaken your bones?
A new study brings a reassuring answer: "Sun-protective" behavior -- wearing long sleeves, seeking shade or using sunscreen -- "was not associated with decreased bone mineral density or increased risk of osteoporotic fracture," the researchers conclu...
Caring for a baby's delicate skin, hair and nails can be intimidating, but five simple steps can make it easier, according to an expert from the American Academy of Dermatology.
"With their tiny hands and feet, babies can seem so fragile and vulnerable," said dermatologist Dr. Kachiu Lee. "However, babies are more resilient than you might think, and parents can maintain good hygiene for t...
If you're at the beach or pool, applying sunscreen before and after you've been in the water is a must, a cancer specialist says.
The intensity of exposure to harmful ultraviolet (UV) rays "is higher under water than it is above water," said Dr. Arun Mavanur. He is a surgical oncologist at the Alvin & Lois Lapidus Cancer Institute at LifeBridge Health, in Baltimore.
When a suspicious skin lesion sends you scurrying to a dermatologist, asking for a full-body skin check could save your life.
Dermatologists are twice as likely to find skin cancer with a full-body check, a new study reveals. More than half of the skin cancers discovered were not in the location the patient was concerned about.
"If the dermatologist did not check their entire body,...
Sun protection is essential as you enjoy the outdoors this summer, a skin expert stresses.
"Skin cancer is the most common cancer in humans so it's important that we do what we can to protect ourselves," Dr. Ida Orengo, a professor of dermatology at Baylor College of Medicine in Houston, said in a school news release.
A U.S.-wide ban on teen use of tanning beds would prevent thousands of cases of skin cancer and save millions in health care costs, researchers say.
Indoor tanning has been linked to an increased risk of melanoma -- the deadliest type of skin cancer -- and the highest risk is among people who start using tanning beds at a young age. Despite that danger, many U.S. teens do.
Most people are familiar with common sun-protection advice, from wearing and reapplying sunscreen to putting on a hat.
But a new Canadian study finds that for people who take certain blood pressure medications, that advice becomes even more critical because those drugs can increase their sensitivity to the sun's harmful ultraviolet (UV) rays.
New research shows that sunnier regions of the United States have lower COVID-19 death rates than cloudier areas, suggesting that the sun's UV rays might somehow provide some protection against the disease.
The effect is not due to better uptake of the healthy "sunshine vitamin," vitamin D, noted the Scottish research team led by Richard...

With many beaches and parks opening in time for Memorial Day, the American Cancer Society is reminding people to practice sun safety.
Overexposing yourself to the sun increases your risk for skin cancer, which is the most common cancer in the United States, with almost 5.5 million cases each year. That's more than breast, colon, lung and prostate cancers combined.
Indoor athletes may be vitamin D-deficient, putting themselves at risk of injury and poor performance, a small study finds.
Researchers assessed vitamin D levels in players on George Mason University's men's and women's basketball teams. For the 2018-2019 season, players were given a supplement with a high dose, low dose or no vitamin D.
The chemicals in sunscreens help shield people from the sun's rays, but they are also absorbed into the body at levels that raise some safety questions, a new study confirms.
The study, by the U.S. Food and Drug Administration (FDA), is a follow-up to a 2019 investigation. Both reached the same conclusion: The active ingredients in popular sunscreens can be absorbed into the blood at ...
Interest in homemade sunscreens is hot, but many of these do-it-yourself brews lack effective sun protection, a new study warns.
Researchers found that only about one-third of homemade sunscreens on the popular information-sharing website Pinterest specified how much sun protection factor (SPF) each "natural" sunblock contained. In some cases, SPF content dipped as low as 2 -- far bel...
For all of those men who view a mustache as a largely ornamental addition to their masculine appearance, a new study reveals it can also guard against lip cancer.
"Mustaches seem to protect the lip the same way that hair protects the scalp," explained study author Dr. Daniel Aires. He is director of dermatology with the University of Kansas Health System. "While this makes intuitive ...
For years, you've been urged to slather on sunscreen before venturing outdoors. But new U.S. Food and Drug Administration data reveals chemicals in sunscreens are absorbed into the human body at levels high enough to raise concerns about potentially toxic effects.
Bloodstream levels of four sunscreen chemicals increased dramatically after test subjects applied spray, lotion and cream...
As you dig into gardening this spring, be sure you don't plant the seeds of skin problems, an expert advises.
"Adverse skin reactions from gardening are very common and may include bug bites and stings, plant-induced rashes, and cuts and infections," said Dr. Sonya Kenkare, a dermatologist in Evergreen Park, Ill.
"While most of these can be easily treated, some can be serio...
Sunscreen may do double duty when you're outside on a summer day, keeping you cool as it protects your skin from the sun's harmful rays.
New research suggests how: When unprotected skin is exposed to the sun's ultraviolet (UV) rays, skin cells typically see a drop in levels of nitric oxide. This compound helps the skin's small blood vessels to relax and widen.
If one of your resolutions for 2019 is to improve your health, reducing your risk of cancer should be part of that goal, a cancer expert says.
While cancer risk factors such as family history and aging can't be controlled, lifestyle changes such as eating right, staying active and not smoking can lower your risk, said Dr. Elias Obeid. He is director of breast, ovarian and prostate can...
